Colombian cyclist Maria-Luisa Calle Williams finished third in the women's point race in the 2004 Athens Olympics but was disqualified after testing positive for Heptaminol, a banned stimulant. Calle appealed the disqualification. Last week, the Court of Arbitration for Sport overruled her disqualification and reinstated Calle's bronze medal.
Calle Williams took Neo-Saldina, an anti-migraine medication. Neo-Saldina contains isometheptene, a substance that transforms into heptaminol during laboratory analyses.
Another high-profile CAS appeal -- that if American cyclist Tyler Hamilton's blood doping suspension -- is still on hold. The Olympic Gold medalist tested positive for blood transfusion on September 11, 2004.
